Key takeaways
- Vertigo is a specific illusion of motion and can feel like spinning, rocking or swaying.
- Benign paroxysmal positional vertigo is common with aging and triggered by head position changes.
- Simple treatments and daily strategies can shorten attacks and reduce fall risk.
Gerard Byrne rolled over in bed one morning in 2023 and felt the room begin to spin. The sensation lasted a few minutes and went away, so he shrugged it off. Almost two weeks later, while bending over to do yard work, the feeling returned in full force, so he went to lie down.
“When I tried to get up, the whole room was spinning for about 20 seconds, like I was on an out-of-control merry-go-round, and it scared the heck out of me,” Byrne says.
That’s vertigo. About 30 percent of people over 50 will experience this unsettling sensation. Defined as “an illusion of motion,” vertigo is a very specific type of dizziness.
“If you have an illusion that you’re moving and you’re not, or have an illusion that the world is moving about you when it’s not, you are having vertigo,” says Dr. Steven Rauch, a Boston-based ear, nose and throat doctor (ENT) and otolaryngologist.
A lot of people assume that vertigo has to be a spinning sensation, says Rauch, who is affiliated with Massachusetts Eye and Ear and Massachusetts General hospitals. But it could be rocking, swaying, tumbling or a feeling of bouncing up, as if you were on a pogo stick.
Causes of vertigo
Many things can bring on vertigo, including inner ear infections, migraines, Ménière’s disease and even some medications, including those used to treat high blood pressure or anxiety.
One of the most common causes, as Byrne, 67, discovered after a doctor visit, is an inner-ear condition with a tongue twister of a name: benign paroxysmal positional vertigo. BPPV can affect people of all ages, but it’s most common in adults over age 50. About half of all people in this age range experience at least one episode of BPPV in their lifetime, according to the Cleveland Clinic.
Along with the “Whoa, what the heck …?” sensation, people may experience lightheadedness and a wonky sense of balance. Queasiness and vomiting may be part of the package.
BPPV occurs when tiny calcium carbonate crystals, which normally reside in an inner-ear organ called the utricle and help you keep your balance, break loose and travel into the semicircular canals of the inner ear. This may be part of the normal aging process.
“BPPV is a degenerative change in the inner ear,” Rauch says. “A degenerative utricle will shed crystals from time to time, like shingles falling off the side of an old house.”
Sometimes a bump on the head dislodges the crystals.
“BPPV is positionally triggered,” says Kim Bell, a San Diego–based doctor of physical therapy who specializes in vestibular rehabilitation. When you move your head in certain ways — dropping it forward to pick something up off the floor or attempting a downward-facing dog yoga pose, for instance — you can cause these crystals to move and bring about an attack of vertigo.
Seasonal allergies may play a role. “It’s interesting — there may even be a link to allergies, though we don’t know if it’s a direct relation,” says Devin McCaslin, director of audiology at the University of Michigan Medical School. “I had one patient who would come the same time every month, once a year, and it would pop up.”
Vertigo is often triggered when you’re lying down. You go to bed feeling perfectly fine, then roll over toward your bad ear to get out of bed in the morning, and wham!
